19 Claims.

This invention relates to machines for operating upon insoles and isillustrated herein with reference to machines for attaching ribbedstrips to insoles to provide sewing ribs thereon.

In machines of the type referred to, a preformed ribbed strip is pressedagainst the outer surface of an insole on a support to attach the stripadhesively to the insole and thereby provide a rib on said surfacesuitable to serve as a sewing rib in constructing a welt shoe. Thesemachines usually operate progressively around the periphery of theinsole, similarly to an insole channeling machine, and the ribbed stripis located relatively to the marginal portion of the insole by a gagewhich engages the edge face of the insole and positions it laterally onthe support relatively to the attaching and feeding mechanism. Since thesewing rib on a Welt insole is normally located at different distancesfrom the edge face of the insole at diiierent portions thereof, forexample, at the shank portion, the forepart or ball portion and aroundthe toe or tip portion, the edge gage in a machine of the type referredto must be shifted relatively to the attaching mechanism to produce thedesired results, that is, the variations in the position of the ribbedstrip or rib widthwise of the insole margin at the different localitiesindicated. These variations in the position of the sewing rib on theinsole are necessary to produce different widths of insole margin orfeather portion at these different localities around the insole which,in turn, are desirable to facilitate the lasting and subsequentperipheral operations on the shoe, and also to produce a properly lastedand well constructed shoe.

The shifting of the edge gage in machines of this type is usuallyaccomplished manually by the operator by means of a handle associatedwith the edge gage mechanism. Since the lateral position of the sewingrib is usually changed at five different places around the periphery ofan insole, the operator must shift the edge gage four or five times whenoperating upon each insole. He must also hold the insole and guide itthrough the machine, taking care to keep it against the edge gage at alltimes. Since the insoles are fed through these machines at a relativelyhigh rate of speed, it will be seen that the operator must be constantlyalert and quick to shift the gage at the proper points around Thissometimes causes fatigue which results in imperfect or defective work.Moreover, even though the op erator is giving his entire attention tothe work' being operated upon, the shifting of the edgegage in thismanner is still subject to variations or errors in timing or judgment sothat all insoles of a particular size or style do not usually haveexactly the same widths of insole margins or feathers at all portionsthereof because the operator does not always shift the edge gage atexactly the same point on each insole operated upon.

An important object of the present invention is to provide a machine ofthe type referred to in which the position of a ribbed strip or sewingrib on the margin of an insole is determined or controlled in a mannerto produce insole margins or feather portions which will be exactly thesame for all insoles of the same size and shape operated upon.

To this end, the invention provides, in accordance with one feature, animproved ribbed strip attaching machine having, in combination, meansfor attaching a ribbed strip to an insole, a member for holding theinsole having means thereon indicating the desired position of a sew ingrib on the insole, and means cooperating with said member for locatingthe ribbed strip in said desired position. As herein illustrated, themember for holding the insole comprises a template having a recess ordepression therein for receiving the insole and holding or supportingthe insole during the attaching operation. According to the presentinvention, the template is also provided with a surface or groovelocated in predetermined relation to the desired position of a sewingrib on the insole.

The means, in the embodiment of the invention illustrated herein, whichcooperates with the holding means or template in positioning the ribbedstrip on the insole comprises a pin or roll normally fixed relatively tothe rib attaching means and adapted to engage the surface or groove inthe template and thereby determine or control the position in which theribbed strip will be applied to the margin of the insole. The ribbedstrip attaching mean in the illustrated machine, as is usual in machinesof this type, operates to press the ribbed strip intermittently againstthe insole and simultaneously to feed the combined insole and stripprogressively through the machine, the insole being normally supportedduring this operation by a rotary table or support. Consequently, whenthe insole is mounted in the holding means or template referred to, theattaching and feeding means operates to feed the insole and templateprogressively across the support as the ribbed strip is being pressedagainst the outer or exposed surface of the insole. The cooperatingmeans or pin referred to, being in engagement with the groove or surfaceon the template, thus causes the latter to move in a predetermined path,thereby determining or controlling the position of the ribbed striprelatively to the edge face of the insole. Since the surface or groovebears a predetermind relationship to the desired position of a sewingrib on the insole, the ribbed strip will be attached to the insole insuch position or relationship. Moreover, every insole operated upon ofthe same size and shape will have exactly the same insole margin rfeather portion because there can be no variations in the foregoingmechanical control of the insole and strip as there can be in the manualoperation of the edge gage mechanism in machines used heretofore.

With the above and other objects and features in view, includingimproved means for varying the entire width'of the margin or featherportion' of th'e' 'insole uniformly throughout the entire periphery ofthe insole while maintaining the predetermined relationship'of theribbed strip to the different portions of the edge face of the insolereferred to above, the invention'will now be" described in "detail inconnection with the accompanying drawings and will thereafter be pointedout in the claims.

No. 175,174, filed July 21,1950. It'should be understood, however, that the invention is notlimited in its utility to embodiment in a machine of this particulartype since it obviously could be used advantageously in other machinesfor operating upon insoles such, for example, as insole channelin andinsole reinforcing machines. As disclosed in the applica tion referredto, the ribbed strip forming and attaching machine illustrated in Fig. 1is provided with a' frame or head 2Q upon which is mounted ribbed stripforming and attaching instrumentalities, the strip forminginstrumentalities including mechanism not shown herein for folding andotherwise shaping a single strip of tape into a tape rib or strip suchas that illustrated in Figs. 3, and '7 to 9, inclusive, this stripforming mechanism being fully disclosed in my copending application.

The machine is also provided with ribbed strip strip and the pressingattaching and feeding means consisting in part of a unitary pressingmember or foot made up of two independent spring-pressed elements '22and 23 (Figs. 3 and 7) arranged to press the ribbed strip intermittentlyagainst the margin of an insole to attach the strip adhesively theretoand being actuated by continuously operating mechanism indicatedgenerally in Figs. 1 and 2 by the numeral 25, this latter'mechanismbeing driven from a motor by a pulley 26 and being under the control ofthe operator through a treadle connected to a treadle rod 28 (Fig. 1).The ribbed strip forming and attaching machine is also provided withvarious other mechanisms 01" meansfor adapting the machine particularlyto perform the desired operation upon the insole and ribbed strip, thesemechanisms including a stationary strip guide 36 (Figs. 1 and 2) forguiding the preformed ribbed strip onto the insole, and a pair ofmeasuring fingers or feelers 3; for automatically controlling theliigtho'f th'e ribbed strip applied to the insole. Since the coiistru'c tionand operation of'th'e'se various 'mecha'n' are fully disclosed in" thecop-ending 'appiicatr n" referred to above, no detaileddescriptionof'siich mechanisms will be giveri' herein'except as" benecessary to insure aprdp'erunderstan ng of the present invention. 7 Themachine is furth'e'rprovided Witha rotary support 3A which is driedagainst height movement during the cante nses th but is adjustableheightwis ebya FE. ya for operating upon insoles whicl differ co cler'fably in thicknesses.

"1): and thereby todetermine'or' control the lateral position of the ribbed striprelatively to the in gin or edge face of the insole while thje strip "isbeing attached to said margin. Thedgegagef shown in the application isof the type disc in Letters Patent" of the"United States 2,326,119,granted August 10, 1943, on an application filed in the name ofFrederick E. Bertrand. This edge gage, as disclosed in the patent, isunder the control of the operator by means of a handle which permits thegage to be shifted into three different predetermined positions to varythe lateral position of the ribbed strip relatively to the edge face ofthe insole at five different portions or sections of the insole aroundthe periphery thereof. This manual control of the edge gage is customarypractice in machines of this type and in some other types of insolemachines, for example, insole channeling and reinforcing machines. Thelocations at which the lateral position of the sewing rib is usuallychanged relatively to the edge face of the insole around the peripherythereof are at the shank portion, at the sides of the forepart andaround the toe portion.

The operator usually places the insole on the support or table of themachine with his left hand and starts the attachment of the ribbed stripat substantially the heel breast line so that the widest margin orfeather of the insole will be located at the shank portion. Afterpassing through the shank portion of the insole, the operator moves theedge gage inwardly toward the support with his right hand while passingaround one side of the forepart of the insole, thereby producing anarrower margin or feather at this portion. He moves the edge gageoutwardly into its third position when passing around the toe portion ofthe insole in order to increase the insole margin or feather a smallamount over what it was at the forepart. He then reverses this procedurewhen passing around the opposite or second margin of the insole untilthe attaching operation terminates at substantially the heel breast lineat this second margin.

It will be seen that this operation requires the constant attention ofthe operator who must be quick and accurate in shifting the edge gagebecause the insole travels at a relatively high rate of speed throughthe machine. Moreover, the operator is not only obliged to shift thegage quickly with his right hand but, as indicated above, he must alsohold the insole and assist in guiding it through the machine with hisleft hand. Consequently, the continued operation upon a large number ofinsoles or for a long period of time is apt to produce fatigue which mayresult in imperfect or faulty work. Another factor to be considered isthat some shoe manufacturers desire to have the sewing ribs on theirinsoles located in exactly the same lateral position on every insole ofthe same size and shape. In other words, they require what are sometimesreferred to as predetermined insole margins which, in insoles havingribbed strips or tapes attached thereto for sewing ribs, means that theribbed strip on every insole of the same size and shape must be locatedin exactly the same lateral position around the entire periphery of theinsole, including the areas referred to where the widths of the insolemargins or feather portions normally change, that is, at the shankportion, the sides of the forepart and at the toe portion, thisexactness applying, of course, to both margins of the insole. Suchaccuracy is practically impossible in a manually controlled mechanismwhere the changes in the lateral position of the sewing rib dependprimarily upon the speed and skill of the operator even though, forordinary purposes and in many cases, manual control of the insolemargins is satisfactory because minor 6 variations in the position ofthe sewing rib in such cases are not important.

In accordance with the present invention, the position of the ribbedstrip or sewing rib relatively to the insole margin or edge face isdetermined or controlled by mechanism which is adapted to provideso-called predetermined insole margins which will be exactly the samefor every insole of the same size and shape operated upon. In otherwords, the present invention provides mechanical means, rather thanmanual, for automatically determining the position in which a ribbedstrip will be attached to the insole in a machine in which the rib orstrip is applied by a progressive or step by step action around theperiphery of the insole as distinguished from a machine in which thesewing rib is applied to, or formed on, the insole by a single pressingor molding operation with the aid, for example, of a matrix, mold orother pressing implement.

In accordance with the present invention, the position of the ribbedstrip relatively to the margin or edge face of the insole is determinedor controlled in the machine by the following mechanism. A fiat plate ortemplate 52 is provided for holding and supporting the insole during thestrip attaching and feeding operations, this template, as illustrated inFigs. 2, 5 and 6, conforming generally in outline to the shape of a solemember and being preferably relatively thin, for example, one quarter tothree-eighths of an inch thick. It may be composed of metal such as ironor steel or it may, if desired, be composed of aluminum or similarmaterial. The upper surface of the template 52 has a depression orrecess 54 formed therein which conforms accurately in outline to theshape of the insole to be operated upon, the depth of this depressionbeing substantially equal to the thickness of the insole so that thelatter will fit into the depression and be held therein with its uppersurface substantially flush with the top face of the template, asillustrated in Fig. 2, the insole shown in that figure being designatedby the letter A.

The bottom surface of the template 52 is provided with a cam groove orslot 56 which, as illus trated in Fig. 6, is relatively narrow in widthand extends around the marginal portion of the template in a positionwhich is located in accordance with the desired position of a sewing ribon the insole mounted in the depression 54. In other words, the groove55 is so shaped and positioned in the template that it correspondsaccurately to the position in which it is desired that the ribbed stripshould be attached to the insole A mounted in the depression 54 in theopposite side of the template. Since the groove 56 is located in aposition which corresponds to that desired for the ribbed strip on theinsole, it will of course be located in a predetermined positionrelatively to the margin or edge face of the insole so that it can beused, as will presently appear, to determine or control the position inwhich the ribbed strip will be attached to the insole with particularreference to the relation of the ribbed strip to the edge face of theinsole at the different regions referred to above, namely, the shankportion, the sides of the forepart and the tip or toe portion. At itsopposite ends the sides of the groove 56 are flared outwardly, as shownin Fig. 6, to provide enlarged openings at these ends to facilitate theuse of the template. The depth of the groove is preferably about onethird the thickness of the template although this may be varied ascircumstances require. Fig. 6 shows predetermined insole margins.

the position of the groove ttrentivery tame edge face of-the template-52 and-also with respect-to the shape of theclepression 54 in. theopposite side of. the template. It will be observed. in that-fig.- urethat the groove bears a diiiferent relationship to the positibn oftheinsole at the differentparts of the periphery of. the latter where thepositien of the ribbed" strip changes, that. is, the shank portion, thesides of the forepart and. theme portion. The precise position of thegroove 56 in the template is usually ascertained by the requirements ofthe shoe manufacturer for whom the insole is to be made, themanufacturer usually furnishing the dimensions which he desires to haveembodied in theinsole for a particular type ofwork, these. dimensionsincluding. the distanees that the sewing rib should be located from the.edge face of theinscle at the shank, forepart and toe portions. Afterthe manufacturer suppliessuch.informationit can be used for. all thedifferent sizesorinsties made for the same manufacturer because.separate templates must be made for eachdifferent. size. Ccnsequentlyifa manufacturer ordersa specified quantity or lot of ihscles,v involvinga number of different sizes, he need only supply one setof dimensions orfigures for the. insole. margins because these same figures can-be usedin constructing the template for each different size The. heel; breastline,.ball line and tip line of the insole A illustrated in Figs. and 6are indicated diagranin'iat'ically inthe latter figure by the brokenlines B, C and D. The position of the sewing rib or ribbeclf striprelatively to the edge face of the.insole,.although changed to providedifferent widths of. insole'margins or feather portions at these threedifferent localities,v are not usually changed exactly on theseparticular lines. Inother words, the changes in the width of the marginor feather of an insole and the points where these changes take placevary in different insoles according to the desires of differentmanufacturers. The broken lines 13,6 and D, there.- fore, merelyindicate the particular points or lines referred to with respect to theinsole A, these points forming the boundaries of the different sectionsof the insole under consideration. It will be seen in Fig.6, that theinsole shown in dotted lines below the groove he hears a difierentrei'atienship, t'dt'he groove at the three regions referred to. Thechanges in insole margins talie place gradually, however, and, asstated, they may vary in amount or position with difierentmanufacturers. Once the exact shape and position of the groove have beendefinitely established in the template with respect to the position andshape of the insole in the depression 54 on its opposite side, allinsoles made with the aid of that template will be exactly the same,thereby producing what has been referred to above as It should bepointed out that the groove 58 illustrated in Fig. 6 is not parallelto'the edge face of the insole indicated in that figure by the dottedoutline of the depression 5i and, furthermore, the groove isnctnecessarily located so that it coincides with the median lineoftheribbed strip which has been attached to the insole illustrated in Fig.5, this strip being. indicated. in that figure by the letter R. Theposition of the groove 553 does, howevenbear a predeterminedrelationshipto the position'of the ribbed strip R shown in Fig. 5 andalsoto'theedge face-of the insole A. The pcsition or'shape -otthegroovewith respect to the edge face of the template 52 is of noconseqiie'neesihce this. edge race perfdnris no reaction in determiningor controlling" the positron ofth'e ribbed strip on the margin or theinsole. Accordingly, blanlitemplates of the same outside shape. orperiphery may be provided in sufficient hiimber to aceommedate a givennumber of sizes of insoles provided the templates are large enough toaccommodate the largest size. This permits a su'flicient number ofblanks to betrovided at one time or with a particular order of insolesto accommodate the entire order since the blanks may then be processedor shaped by suitable machinery into the special templates required foreach different'size of insole in acetic with the dimensions" supplied bythe mane facturer. Such procedure will materially reduce the expenseinvolved in providing the templates required for a substantial number ofinsoles. A hole 51 is provided at the heelend of the tem= plate tofacilitate the removal or the insolefrom the depression 54 after theribbed strip has been attachedto the insole in the attaching machine.

The template 52* is utilized in a ribbed strip attaching machine,forexample, the machine disclosed in the copending application, in thefollowing manner. As described in said application, the edge gagemechanism illustrated therein is carried by a bracket 58 (Figs. 1 and 3)ad"- justably mountedifor movement forwardly and rearwardly of themachine in a i -slot 55' formed in the casting Silt,v the brackettir'beihg secured in position by a" binding" screw 62'. The bracket 58may, if desired, be removed completely from the T-slot, thereby removingthe entire gage mechanism from the machine to permit another type ofgage mechanism to be mounted therein. The bracket 58 of the presentconstruction has an up standing portion 64% (Fig. 3) located at theright of the casting 38 and provided with a vertical desired; being inthe former a roll to reducefric Hen. The pin i l'is arranged to enterthe groove 53 the template 5'2 and thereby to control mevementor thetemplate relatively'to the'suppert 34",-as' will presently be described.The posican or the pinlfl forwardly and rearwardly of the machine withrespect to the vertical axis 36 about which the support rotates issomewhat critical becauseit infl-uen'cesthe movement of the insole whenthe latter is fed, during the ribbed strip attaching operation, underthe action of the unitary 'presser foot 22; 23:. Accordingly,the'p'osition of the bracket 53 forwardly and rearwardlyof the machineis adjustable in order thatv the' pin it may be located in exactly theright'position relatively to the center of the axis it: This adjustmentis accomplished by means of: an adjusting screw it threaded into a platels'secured by screws tothe bracket 58-, the screw b'eing'arranged toengage asurface formed on the casting; 38. When'the position of thebracket :ter has'been. once established; the screw it may be securedinlposition by a lock nut t l.- As disclosedin the applicationreferred-to, the'casting 3'8 isadjustable heightwise of the machine tolocate the supporttin a proper heightwise position relatively to thepresser foot 22, 23 by means only when the difference in thicknessbecomes greater than this range. When the support is adjusted heightwisefor insoles which differ substantially in thickness, the pin M will movewith the support and thus retain its original heightwise positionrelatively to the top surface of the support and relatively to thegroove 55 in the template 52. As shown in Figs. 1 and 3, the support iscut away around the margin of its upper surface to form a step orshoulder 84 at the outer edge of said surface and thus provide spaceinto which the arm 12 can extend to permit the pin M to engage thegroove 56 when the template is resting on the support, the templateextending laterally a considerable distance beyond the support at theside where the ribbed strip is to be attached. As indicated above, thegage 68 and pin M are adjustable widthwise or laterally of the machineor, specifically, widthwise of the presser foot 22, 23 and support 34,by the slot and screw arrangement H1 (Fig. 3) which secures the gage inthe guideway 56. This lateral adjustment of the gage 68 permits theall-over width of the insole margin or feather to be varied uniformlyaround the entire periphery of the insole. In other words, adjustment ofthe gage 68 widthwise of the machine, moves or shifts the initialwidthwise position of the template a corresponding amount relatively tothe presser foot 22, 23 and thereby widens or narrows the margin orfeather portion of the insole uniformly around its entire periphery anamount equal to the amount which the gage was adjusted. Consequently,the entire insole margin or feather will be wider or narrower by thatsame amount although the ribbed strip as a whole will still maintain itsinitial predetermined relationship to the different portions of the edgeface of the insole referred to above, that is, the shank portion, thesides of the forepart and the toe portion of the insole. Stated inanother way, the adjustment of the gage 68 laterally of the machinechanges the width of the insole margin or feather uniformly around theentire periphery of the insole without altering the predeterminedrelationship of the ribbed strip to the edge face of the insole at thedilferent portions referred to. This is particularly advantageous whenoperating upon insoles which are to be used with shoe uppers that varyconsiderably in thickness. Such adjustment permits the operator tocompensate for the different thicknesses of shoe uppers by merelychanging the position of the ribbed strip as a unit relatively to themargin or feather portion of the insole.

Although the use of the machine in obtaining exact or predeterminedinsole margins when attaching ribbed strips to insoles will be apparentfrom the foregoing description, a brief summary of its operation will begiven here for the purpose of clearness. The insole A is mounted in thedepression or recess 54 in the template 52 with the outer orsole-engaging sur-, face of the insole facing upwardly, the marginalportion of this surface, at least rearwardly to the heel breast line,having, been previously coated with a suitable pressure-responsivecement E (Fig. 2), which has been allowed to dry in the usual manner.The template is placed on the support 34 with the insole facingupwardly, as illustrated in Fig. 2, and with the rear or heel end of thetemplate extending rearwardly of the machine to engage a heel gage 86(Fig, 1) provided in the machine and arranged to position the insoleinitially so that its heel breast line B (Fig. 6) is locatedsubstantially under the rearward edge of the presser foot unit 22, 23.In placing the template on the support, the operator introduces the pin14 on the gage 68 into the groove in the lower surface of the template,this operation being facilitated, as stated above, by the flaring sidesof the groove at the opposite ends thereof at the rear or heel portionof the template. The operator starts the operation of the machine bydepressing the treadle connected to the treadle rod 28 and the presserfoot 22, 23 commences to press the ribbed strip R. intermittentlyagainst the insole and also to feed the insole and strip, together withthe template, rearwardly of the machine to attach the strip adhesivelyto the margin of the insole, the heel gage having been raisedautomatically into an inoperative position upon treadling the machine.The position in which the ribbed strip R. is initially attached to theinsole in the vicinity of the heel breast line is illustrated in Fig. '7which also shows the unitary presser foot 22, 23 pressing the stripagainst the margin of the insole while holding the two-ply rib portionof the strip in a substantially vertical position because the presserfoot members in the machine disclosed in the copending applicationsurround this rib portion while they are pressing against the oppositeflanges of the ribbed strip and are simultaneously feeding the insoleand strip. The attaching and feeding operation continues progressivelyaround the margin of the insole, as illustrated in Figs. 2 and '7 to 9,inclusive, during which time the template is shifted widthwise of thepresser foot 22, 23 by reason of the pin 14 engaging the groove 56.Although the operator will usually hold or steady the template on theSupport 34 during the attaching operation. he is not obliged to guidethe template or otherwise control its movement with the insole on thesupport because the pin i l in the groove 56 performs this functionautomatically without attention on the part of the operator,irrespective of the speed at which the machine is operated. When theattaching operation reaches the forepart of the insole, the ribbed stripwill be located closer to the edge face of the insole, as shown in Fig.8, due to the relation of this portion of the groove 56 to the edge faceof the insole. As stated above, the position in which the ribbed stri Rwill be located with respect to the edge face of the insole at theforepart thereof may vary somewhat with different manufacturers but, inall cases, it will be located considerably closer the edge of the insolethan it is at the shank portion where a wider insole margin is desired.

' The operation proceeds around the toe portion of the insole and hereth groove 56 locates the ribbed strip somewhat further inwardly from theedge face of the insole, as shown in Fig. 9, after which the insole isfed forwardly along its opposite or second margin where the position ofthe ribbed strip is again determined and controlled automatically at theside of the forepart and at the shank portion by the engagement of thegroove 53 with the pin 14. When the attaching operation returns to theheel breast line at the opposite margin of the insole, the rib attachingmechanism is stopped automatically by the fingers 32, as described in micopending application, and a knife 8 8 =(-Fig. provided on the machineis actuated either-manually or automatically to 'sever the "ribbed stripfrom the insole, this severing operation taking placeat a point which issubstantially in transverse alinement with the starting position of theribbed strip at the opposite or rst mar of the insole as shown in Fig.5. The operator then removes the template from the support '34 andpresses the insole out of the depression tit in the template through thehole '5! at the heel end thereof. The template is then ready to receiveanother insole of the same size and shape preparatory to attaching "aribbed strip to that insole.

It might be pointed out with respect to Figs. 7 to 9, inc1usive, thatthe presser foot 22, 28, the rotary support 34 and the pin 14, asillustrated therein, remain in stationary -'or fixed positions widthwiseof the machine While the template 52 and insole A shift laterally on thesupport 34 during the feeding movement in accordance with the varyinglateral positions of the groove 56 in the template. Consequently,although the ribs R in these three figures appear to be located in thesame widthwi'se position or in vertical alinement with "each other, theposition of the ribbed strip relatively to the edge face of the insolehas actually changed widthwise in accord-- ance with the shape orposition of the groove 56, as is clearly shown by a comparison ofthepositions of th ribbed Strips R, shown in these three figures "withrespect to the edge faces of the different portions of the insoleillustrated in said figures. After the unitary presser foot 22, 23 hasleft the ribbed strip R, the two-ply rib portion of the strip bendsinwardly away from the edge face of the insole a small amount, asillustrated in Fi s. *8 and 9, owing to the manner in which the ribbedstri-o was formed in the ribbed strip formin and attachin machine.

Having thus described my invention what claim as new and desire tosecure by Letters Patent of the United States is:
